安装

In order to use these functions you must compile PHP with lzf support
by using the --with-lzf[=DIR]
configure option. You may also pass
--enable-lzf-better-compression
to
optimize LZF for space rather than speed.

Windows users will enable php_lzf.dll inside
of php.ini in order to use these functions.
